Beta diversity of the cervical microbiota. Principal Coordinates Analysis (PCoA) plots of the weighted UniFrac distances of the cervical microbiota coloured according to a) community state type (CST), b) bacterial vaginosis (BV) findings, c) human papillomavirus (HPV) infection status, and d) high-risk (HR)-HPV infection status. The first three principal coordinate (PC) axes and the percentage variation explained by each (PC1: 48%, PC2: 9%, and PC3: 8%) are shown. Each solid point represents a bacterial community.
